1. Zɛnki ɔkisizɛni (ZnO) .

Bolo fɛnw:

• Mugu finman, kasa tɛ min na, a girinya kɛrɛnkɛrɛnnen ka bon (5,6 g/cm3).

• A wuliyɔrɔ: 1 975°C; fɛnɲɛnamafagalan : 2,008–2,029.

• Reactivité haute i n’a fɔ vulcanization activateur.

• UV-blocking ani banakisɛfagalanw tali.

Nafa minnu bɛ a la:

• A bɛ kisɛkisɛ vulkanizeli teliya (a bɛ kɛnɛya waati dɔgɔya ni 20–30%).

• A bɛ masinko nafaw ɲɛ (sɛgɛsɛgɛli fanga +15–25%, janya kari waati +10–15%).

• FDA ka sɔnni kɛ dumuni ni ɲɔgɔn cɛ baarakɛcogo la (21 CFR 172.480).

• Sigida lakanani (min tɛ baga ye, a bɛ se ka segin a cogo kɔrɔ la).

Baarakɛcogo:

• Pneu : Pneu radiale sogo minnu sirilen don ni nɛgɛ ye (o bɛ dɔ fara nɔrɔli kan lastikuw ni nɛgɛ cɛ).

• Sennasanbaraw : Kɛnɛmafɛnw (a bɛ sɔgɔsɔgɔninjɛ kunbɛncogo ɲɛ, ASTM D5963: 50–80 mm3 bɔnɛ).

• Furakɛcogo: Opereli ganw (banakisɛfagalanw lakanani, ASTM E2149).

• Nɛgɛw : Lastikuw ni nɛgɛ sirili (o bɛ dɔ fara a ɲɛkisɛ fanga kan ni 30–40%).

2. Résine Fenolique (Fɛnoliki Resin).

Bolo fɛnw:

• Polimɛri min bɛ thermosetting ni a ka crosslink density ka bon.

• Funteni kunbɛnni : Aw bɛ to ka a kɛ fo ka se 180°C ma (a bɛ kɛ 250°C waati ni waati).

• A ka gɛlɛn kosɛbɛ (modulus: 2–4 GPa) ani a hakɛ sabatili.

• Furakɛcogo min bɛ asidiw, basiw ani furajiw kɛlɛ.

Nafa minnu bɛ a la:

• A bɛ jɔli barika bonya (a bɛ dɔ fara a gɛlɛya kan ni 10–20 Shore A ye).

• Tasuma-fagalan (UL94 V-0 hakɛ min tɛ halojeni fara a kan).

• A musaka ka dɔgɔn ni i y’a suma ni thermoplastique kɛrɛnkɛrɛnnenw ye.

• Furakɛcogo minnu bɛ se ka kɛ ka kɛɲɛ ni mɔgɔw sago ye (asidi-katalizi walima funteni-activé).

Baarakɛcogo:

• Pneu : Kɛrɛfɛla fɛnw (a bɛ tigɛcogo ɲɛ, ASTM D624).

• Industri cɛsirilanw : Cɛsirilan minnu bɛ taa ni fɛnw ye minnu bɛ kɛ sigidaw la minnu funteni ka bon (misali la, siman iziniw).

• Fɛn minnu bɛ sɔgɔsɔgɔ : Freinw (a bɛ sɔgɔsɔgɔninjɛ coefficient mara 0,35–0,45 la 200°C kɔrɔ).

• Foundry: Core sand binders (a bɛ gazi jiginni dɔgɔya casting waati).
